A man is driving down a country road in the middle of dairy farm country when his car stalls inexplicably. He gets out and raises the hood to see if he can find out what's happened.
A brown and white cow slowly lumbers over to the car and sticks her head under the hood beside the man. After a moment the cow looks at the man and says, "Looks like a bad carburetor to me." Then she walks back into the field and begins grazing again.
Amazed, the man walks back to the nearby farmhouse and asks the man who answers the door, "Hey, Mister, is that your cow in the field?"
"The brown and white one? Yep, that's old Bessie."
"Well my car's broken down, and she just said, 'Looks like a bad carburetor to me.'"
The farmer shakes his head. "Don't mind old Bessie," he says. "She don't know a thing about cars."
